Abstract

The surface variables and the characteristics of satellite radiation budget field about a serious snow disaster were analyzed in October 1985 over Central Qinghai-Xizang Plateau,and the causing snow disaster were preliminary researched.The results show that the range of precipitation(≥8 mm) and snow depth(≥5 cm) is almost equal.The lag-cooling effect of the snow cover is stronger,continuing time is about five months.The calculated results with satellite radiation data show that the albedo is important in the radiation budget field of earth-atmospheric system.In November,every variable in the central area of snow cover is getting to the largest:or so,albedo anomaly is high as 16%,OLR is low as 185.6 W/m2 and the net radiation is-25.4 W/m2.The preliminary result were discovered,which there will be serious snow disaster in the winter or/and the next spring over Plateau,if the earth-quake(Ms≥7) is appeared between the western Tianshan and Pamier(73°~75°E) or in the Central Plateau(32°~35°N,85°~100°E) when Ms≥5.9 in last half a year.
